Incubation Temp, too hot?

Its 91F outsided today. And its just about the same in my room where 12 of my 8oz jars are incubating very very nicely. The $2-3 thermometor is reading 91F. The cardboard box, glass, and metal jar lids were all warm to the touch. when I picked them up to check them out, i could feel that they had beed heated and warmed by the high Temperatures.
This happened once before a few weeks ago. we had a real hot day here and the temp read 90+F. I moved them from the third floor where my room is and placed them in a closet in the basment were it is never going to break 90F or high 80's for that matter.
My Question is. what is the point where you say "ok one more damn degree and these bastards are going to experience thermal death"? I understand that high 80's are ideal for incubation temperature. well how about even higher. low low 90'sF like 91F 92F? From me to you i think that the growth was explosive from last night to the time I checked them today and noticed that they were getting lightly baked. I think they grew as much as they would in a day or two or three of mid 80F temperatures as they did getting baked by 91F temperatures for 12hours.
well they are in the basment now. I dont want to take any chances. like i said it got hot a week or two ago and they were in low 90's for atleast a good day or a good amount of hours. moved them down here and when the heat spell was over i moved them back upstairs where its mid to high 80's.
where do you draw a fine line with temperature? If any of you have successfully incubated at low 90F plz let me know how it went. I would leave them up there but i weigh therisk with reward. and they are doing excellent. dont want to get greedy and pay for it. thanks.

Ideal temp is 84, Thermal death occurs at 106. Hope that helps.

ok. thats good. still need more feedback. low 90'sF is a far cry from 106F. at that rate I would like to think that it is more than safe to keep them in the low 90'sF or even higher mid 90'sF. I doubt that it is going to get that hot. man 106 huh? i feel like bringing them back upstairs right now so they can bath in that heat.

At temps above the mid 80's the bacteria have a greater advantage than the mycelium in growing conditions.

i had 24 jars in a room at about 74 degrees. I took them and moved them to a 86 degree room and they seem to be growing twice as fast. I found they grow the fastest in the mid to upper 80's. The rate the mycelium is covering the growing medium is noticabely faster.

ok good frog. that sounds true. Have you expeinced that personally? contamination of jars in high temeratures? the jars are about half way colonized. all sites are connection with one another and making thier way down to the bottom of the jar. so the mycelium is fairly strong to ward off bacteria?
keep the feedback and experience coming. even if its repetative.

This is to both influxx and bladerunnerss: Incubating at 70's is ok, but like you noticed colonization is MUCH faster in the mid 80's. Your best chance to ward off contams it to colonize the jar ASAP. By having temps in the 90's the bacteria grows faster than the mycelium. 90+ temps don't guarentee contams, but it isn't helping you. For optimum results ~84 F is recommended. I hope this helps you out.

hmmmmm. the fact that "By having temps in the 90's the bacteria grows faster than the mycelium." is discouraging. i know what to do. I can take half the jars and leave them here where it is mid 80's and take the rest upstairs where its really hot and see what happens.
keep the info coming guys. thanks again frog.

ok I moved the jars back upstairs where its 90F. they day is getting on and its starting to get cooler so i dont think that they will be at 90+F.
I think the growth is explosive at high 80's and low 90's plz if anyone incubated at low90's and had a problem let me know.

I dont understand. well its going to get cooler at night. wouldnt you want the heat to stay with the jars? like now the sun is down and in not near my jars w/ thomometer but its probably low to mid 80's. whereas you would like it to stay mid to high 80's. yes?
I think that the higher temperatures 90F did the colonization justice. i was really amazed. Im hoping it goes up to 90 or 91 again tomorrow. just not too hot i dont want them to die. I got scared when i touched them. everything was warm. the glass and lids were not room temperature. the feel of the glass was damn warm. and i said oh S!@# its been like this for probably 4-5 hours. Then i examined the mycelium trying to see if there was damage. how would you tell there is thermal damage? the only thing i noticed is that had grown even more since the last time i checked was the night before, probably 12 hours earlier.
has anyone killed colonizing jars at 90F?
common guys i need more feedback from all of you?

86 degrees is optimal, tests show it and it is stated in the FAQs.
Pic from FAQ
Link to FAQ http://shroomery.org/faq/faq.php?display=faq&nr=33&catnr=3&prog=1&lang=en&onlynewfaq=1
Hope that helps clear up the optimal temp mumbo-jumbo.... Fd

Thanks Fd3000! I was thinking of that pic, but couldn't remember where I saw it.

I agree that 86 is optimal but let's not forget that the mycelia will produce a couple of degrees therefore the ideal temp to adjust the incubator to is 84. For best results, since you can't quite cool to a perfect temp, I beleive it would be better to move the jars to a the basement and use an aquarium heater sealed in a jug of water to heat the incubator to a perfect 84. Trying it both ways is pretty smart. For future reference as well as to decrease the chances of a total loss. But if at all possible it's best to keep the mycelia at optimum temps. Hope that helps.
